Hello there sporty people. I have a problem with my 91 sporty from 6 months ago when she decided to start making pretty bad knocking noises from under the right hand side wheel, it was in a pattern as I drove forward. I called out green flag and he said it was the half-shaft. So I purchased one second hand and got it fitted. Got it back from garage and went home in it, fine. The next day I went out in her and she decided to make the same noise banging or thumping from under the right wheel in a pattern, which then decided to go again later that day, untill now. Green flag again said it is the half shaft but when i went back out in her she decided not to make the thumping noise. Is it anything to do with the hub, is it missing some how or other. Give us a clue someone. Cheers, Scott.
